RAIL-JOINT.

Specification 01 Letters Patent.

Patented May 23, 1911.

Application filed February 16, 1911. Serial No. 608,939.

To all whom it may concern:

Be it known that I, CLAYTON DETWILER, a citizen of the United States,residing at Philadelphia, in.the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inRail-Joints, of which the following is a specification.

My invention relates to improvements in rail joints, the object of theinvention being to provide an improved joint which will preventindependent movement of the rails in any direction, and which willdispense altogeiher with the necessity for fish plates and b0 ts.

A further object is to provide an improved joint of this character whichenables a rail to be removed and replaced whenever occasion may require,and which when the rails are is position, they will be securely lockedand held against movement.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations and arrangements ofparts, as will be more fully hereinafter described and pointed out inthe claims.

In the accompanying drawings: Figure 1, is a perspective viewillustrating my improved rail joint. Fig. 2, is a top plan view. Fig. 3,is a perspective view of the clamping plate 12. Fig. 4, is a view inhorizontal longitudinal section taken through the web of the rails. Fig.5, is a view in section on the line 5-5, of Fig. 4:. Fig. 6, is a viewin section on the line 66 of Fig. 1, and Fig. 7, illustrates inperspective the meeting ends of adjacent rails.

1, and 2, represent rails, both of these rails being precisely alike butreversely p0- sitioned. In other words, they are very different instructure at their-opposite ends, and the adjoining of two rails onlyare illustrated. The head 3 of rail 1 is cut away as shown in Fig. 7 andthe web portion 1 is notched in its upper edge as shown at 5. Rail 2 atits end, is of inverted U-shape as shown clearly in Fig. 7, so as tostraddle the web 4 of rail 1, and in this inverted U-shaped end, a lugor key 6 is provided to enter the notch 5 and prevent any independentlongitudinal movement of the rails. This rail 2, at its point ofjuncture with rail 1, has its base flanges 7 elevated so as to rest onthe base flanges 8 of rail 1, the shoulder 9 being formed to receive theends of flanges 8. The flanges 7 above referred to, are cut out as shownat 10, so as to accommodate the head 3 of rail 1, and permit rail 2 tobe positioned when moved vertically, as it is to be understood that theflanges 7 extend beyond the point of juncture of the heads 3 of the tworails. Upwardly projecting longitudinal flanges 11 are provided at theouter edges of base flanges 7, and an improved clamping plate 12 isadapted to engage over these flanges 11. The clamping plate 12 extendstransversely below the rails 1 and 2, and its ends are bent upward asshown at 13, then bent inward as shown at 14,-, and then downward asshown at 15 forming angles which, when the clamping plate is slid ontothe joint, will engage over the flanges 11 as clearly shown. This plate12 must be slid onto the joint longitudinally of the rails, whichclamping action is facilitated by the curved formation of base flanges 7and flanges 11 as shown at 16, and the movement of the plate isfacilitated by means of lugs 17 at the respective ends of the plate.

To prevent any longitudinal movement of the clamping plate when once inposition, a cotter pin or other locking device 18 is located inregistering openings or recesses 19 and 20 in the clamping end of plate12, and flange 11 respectively, thus securely locking the partstogether.

Various slight changes might be made in the general form and arrangementof parts described without departing from my invention, and hence I donot limit myself to the precise details set forth, but consider myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: p

1. In a rail joint, the combination of two rails, one rail having itshead cut away exposing its web at the end, of base flanges on the otherrail, adapted to rest upon the flanges of the first-mentioned rail, saidlastmentioned rail of inverted U-shape to straddle the exposed web ofthe first-mentioned rail, said overlying base flanges having upwardlyprojecting flanges at their outer edges, and a clamping plate projectingunder the rails at the joint and having bent ends engaging over saidupwardly projecting flanges, substantially as described.

2. In a rail joint, the combination of two rails, one rail having itshead cut away eX posing its web at the end, of base flanges on the otherrail, adapted to rest upon the flanges of the first-mentioned rail, saidlastmentioned rail of inverted U-shape to straddle the exposed web ofthe first-mentioned rail, said overlying base flanges having upwardlyprojecting flanges at their outer edges a clamping plate projectingunder the rails at the joint and having bent ends engaging over saidupwardly projecting flanges,-said upwardly projecting flanges and saidclamping plate having registering openings and a locking pin in saidopenings, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
